Hi, I am working on a project to display the temperature from a thermistor on a LCD display. Here is a list of components I am using. hd44780 PIC18F4520 LM35cz I am working in assembly language and my question is how to take the 10 bit ADC result my PIC gives me in the ADRES register and display it in Fahrenheit on the LCD. I am pretty much
The hd44780 chipset offers either 8-bit or 4-bit data I/O, not 16-bit. The interface and coding method is similar to utilizing the device with an 8-bit PIC. There are numerous hd44780 compatible LCD libraries available. Are you coding in C or Assembly Language? If C, what compiler are you using? BigDog

If you don't have a loop in main() yourself, then I guess that Isis is restarting the program when your code finishes. Put a while(1); after the last line in your code (before the last '}' in main) so that the program keeps running, doing nothing. For the writing lines, the hd44780 is very simple and designed for two lines o
You can create header file, it's extension is .h. Then, in the C code, you can include the File Name.h. Ex, code for LCD hd44780, the with the header file. Beginner now, not know how the LCD operation, just use the function/header created by m
You need to try first if ST7066U is compatible with hd44780. Connect your LCD in 4 bit mode. The LCD library of mikroC is so easy to use.
i have written a code in mikro c without using lcd library, my lcd has a ST7066U driver and i have written for 8-bit interfacing. now i have test the code in proteus 7 but nothing is showing. Note: i am not using lcd library given in mikroc because the code is for hd44780 and for 4-bit. Is there a library for 8 bit interfacing? And is ST7066U

The solar panel driver uses five modules: main board power supply module bus X axis controller Y axis controller multi module that supports: display hd44780 keyboard PS/2 [
As tpetar said, some good photos might help. When you say "(3x16)" - what exactly are you referring to? Numbers of pins? Display size (do you mean 2x16)? Many small LCD displays are hd44780 compatible, often with the semi-standard pinout too. Let's see some photos.
I'm fairly certain that the ST7066U is directly compatible with the hd44780 - so you could probably use Proteus' hd44780 module.
That is most likely an hd44780 compatible (like the LM2338SGR) type - with similar pinout to almost every other hd44780 type. Hitachi hd44780 LCD controller - Wikipedia, the free encyclopedia You can try it out (although there is a risk it will be damaged if I am wrong!) by: Conne
Most LCD's have a common command set, here is a link to some info. hd44780 Commands For formatting Your editor should have an option to use TABS or Spaces. If you convert the tabs to spaces, your indentation will be ok.
This may help with the display, it explains the commands for the HD 44780 and pin connections hd44780 Controlled LCD
It is an issue of the scope of microcontrollers, especially from the side of programming. Unfortunately, libraries supporting peripherals available on the Internet are poorly documented and often little universal. TavrLib library
For driving motor you can build discrete H-bridge (which is general way to control DC motor rotation direction) or use some integrated bridge like L298, LMD18201 or similar. For buttons see any microcontroller related tutorial, this is the most basic thing ever. As for LCD, if is has hd44780 compatible controller (which i'm almost sure it has) you
Hey guys, I need a little help displaying the time on a hd44780 lcd. Compiling on PIC basic Pro. There are two of us having the same issue. Below is the code I used. The display is Time=00:00:00 Date=00:00:00 Any suggestions would be helpful, not very good at these things. I will owe you a burrito if we can get her running.
I should reset power of both PIC and LCD to bring LCD back to normal. Does it work? I assume that you are using an industry standard Hitachi hd44780 compatible LCD. The dataheet has detailed instructions how to perform a reset without cycling the LCD power.
For such tasks I usually use sprintf function and then send the string to the display. How to send the string to display you can find on the net. Or you can write you own functions for handling LCD, the hd44780 protocol is really simple. Sprintf works just the same as typical printf from basic C courses apart from the fact that it prints
Assuming that you are referring to a hd44780 display and not a graphic one then the characters are predefined and you cant rotate them. There are 64 bytes CGRAM available for the user allowing up to eight 5*8 pixel characters or patterns, if you just want to show a few letters rotated then you can use it but not to show the complete alphabet rotate
